Benefits of technology

"The patent describes how to create an article with a film that has a Fresnel lens and a design that appears to be three-dimensional. The design can be placed above or below the Fresnel lens. The film can also contain holographic snowflakes or a winter scene to create a snow globe effect. The technical effect of this invention is the creation of a unique and interesting article that can be used for decorative purposes or as a gift."

Problems solved by technology

In addition, the printing was opaque such that any portion of a Fresnel lens that happened to be printed upon was intentionally obscured by the printing process.

Embodiment Construction

[0024]FIGS. 1A and 1B illustrate cross-sections of an aspheric conventional lens 16 and a Fresnel lens 17 having the same focal length. In general, positive focal length Fresnel lenses are almost universally planoconvex having a flat surface 18 and a jagged convex surface 19 as illustrated. A positive focal length Fresnel lens transforms the thicker aspheric lens into a much thinner lens having the same optical properties. In a Fresnel lens, the bulk of the material is reduced by the extraction of multiple coaxial annular cylinders 20 of material. The contour of the aspheric lens's convex surface 19 is thus approximated by right circular cylindrical portions intersected by conical portions having inclined surfaces 22. The inclined surfaces feel like multiple grooves when running your fingernail across the jagged convex surface 19. The height of the cylinders 20 do not contribute to the lens's optical properties enabling Fresnel lenses to be made extremely thin compared to the same f...

Abstract

A film having a Fresnel lens is placed adjacent a design to create a three-dimensional image. The film can be used separately or laminated to a substrate to create enclosures such as cartons, dispensers, or containers.

Description

BACKGROUND[0001]Prismatic materials that capture and reflect light in different directions are known to convey the appearance of depth or three-dimensions on a flat surface. Prismatic materials are useful for a wide variety of applications such as decorative films, wrapping paper, packaging, and containers.[0002]One example of a prismatic material is a Fresnel lens, which can be created in a film layer, and the resulting film metallized or backed by light reflecting material. Such materials can produce an image of a ball or globe appearing to have three-dimensions. Prismatic material of this type is available as a repeating Fresnel lens pattern film laminate under the trademark Multi-Lens™ by Coburn Corporation, Lakewood, N.J. A tissue carton utilizing this material is disclosed in U.S. Pat. No. D459,221 entitled Tissue Carton Having Prismatic Sidewalls issued to Springer et al. on Jun. 25, 2002, and herein incorporated by reference in a consistent manner.[0003]Another example of a ...
